The Zeiss Conquest is truly one of my favorite rifle scopes.  I've used it for a few years on my varmint rifle and it's seen some tough conditions but it has never let me down.

Every time I look through the scope I am amazed at how easy it is to acquire the target.  When your trying to take a quick shot at a difficult angle that speed makes a big difference.  I've some other high end scopes that were noticeably more difficult to get everything lined up.  

The Rapid-Z reticles basically offer yardage and windage marks and come in several different models which are designed to work with different caliber rifles.  Once you've taken the time to get the right scope/reticle/rifle combination it can really make long range shooting much easier.  Here's a list of the different models available.

Rapid-Z 600:  Standard Calibers: .243, .270, .30-06, .300 Win Mag, .325 WSM, etc.

Rapid-Z 800:  Ultra Mags: .300 Ultra Mag, .338 Ultra Mag, etc.

Rapid-Z 1000:  Long Range: .308 Win.

Rapid-Z Varmint: Fast, Lightweight: .204 Ruger, .220 Swift, .22-250, etc.

The process of getting the right reticle can a little confusing, but the Rapid-Z Calculator on the Zeiss website has made it pretty simple.  After you've input your load data and selected your reticle the calculator tells you what power your scope needs to be on in order for the yardage marks to be accurate.  Once you've done this and zeroed your rifle as they recommend this setup can work very well.

These ballistic reticles can be easier in some ways than using a BDC adjustable turret especially when your target is changing ranges quickly.  Being able to see all yardages and make quick adjustments without having to turn a turret can be an advantage.  However for very long ranges and exact precision the turret is probably a better option and more customizable to your particular load.
